Genetics of seed yield and neurotoxin content in grasspea (Lathyrus sativus L.)

Abstract

The present study was undertaken to know the genetic nature of grain yield and neurotoxin involving low ODAP parents through generation mean analysis of four grasspea (Lathyrus sativus L.) crosses, Biol-203 x Biol-222 (Cl ), Biol 203 x RLS-9 (C2), Biol-222 x BioR-231 (C3), Biol-222 x Pusa-24 (C4). Six generations viz. Pl , P2, Fl , F2 BC1Pl and BC1P2 were grown at Indira Gandhi Agricultural University, Raipur during winter 1997-98, in RBD with three replications accommodating six rows of each F2 and single rows for other generations. Observations (Table 1) were recorded on single plants and ODAP content in dry seeds was estimated following Rao [1].
